Smart contract audits are essential for crypto projects, but they address only one part of your security posture. Many projects invest heavily in blockchain security while neglecting the critical Web2 infrastructure that connects users to their platforms. This oversight creates significant vulnerabilities that attackers regularly exploit.
The Incomplete Security Approach
Most crypto projects follow a standard security playbook:
- Multiple smart contract audits
- Bug bounty programs
- Formal verification
- Security monitoring for on-chain activity
While these measures are necessary, they fail to address a fundamental reality: users access your platform through traditional web infrastructure. This creates a security blind spot that sophisticated attackers target.
The Missing Elements in Your Security Stack
A comprehensive security approach for crypto projects must include these often-overlooked elements:
1. Domain Registrar Security
Your domain registrar represents a single point of failure. If compromised, attackers can redirect all traffic to malicious sites without touching your blockchain infrastructure.
Essential measures include:
- Registry locks (not just registrar locks)
- Hardware-based multi-factor authentication
- IP-restricted access
- Specialized registrars with crypto-specific security protocols
2. DNS Infrastructure Protection
DNS serves as the translation layer between human-readable domain names and machine-readable addresses. Compromised DNS can redirect users to phishing sites that perfectly mimic your interface.
Required protections:
- DNSSEC implementation and maintenance
- DNS monitoring with real-time alerts
- Redundant DNS providers
- Nameserver delegation security
3. Frontend Security Controls
Your application frontend serves as the interface between users and your smart contracts. Compromised frontends can manipulate transaction data before it reaches the blockchain.
Critical safeguards:
- Subresource Integrity (SRI) for all JavaScript resources
- Content Security Policy implementation
- Regular security scanning of frontend code
- Immutable deployments with integrity verification
4. Phishing Protection and Monitoring
Attackers frequently create convincing replicas of crypto platforms to steal user credentials and funds.
Necessary countermeasures:
- Domain monitoring for typosquatting and homoglyphs
- Automated takedown services
- User education resources
- Browser extension verification tools
5. Access Control and Governance
Internal threats and compromised team accounts can lead to security breaches.
Required controls:
- Role-based access control for all systems
- Multi-signature requirements for critical changes
- Privileged access management
- Regular access reviews and rotations
The Complete Crypto Security Checklist
Below is a comprehensive security checklist that addresses both blockchain and traditional infrastructure security:
Smart Contract Security
- Multiple independent audits
- Formal verification where applicable
- Comprehensive test coverage
- Bug bounty program
- Monitoring for suspicious transactions
Domain Security
- Registry locks implemented
- Hardware-based MFA for registrar access
- Specialized registrar with crypto experience
- Regular account access reviews
- Monitoring for unauthorized changes
DNS Security
- DNSSEC properly implemented
- Redundant DNS providers
- Nameserver monitoring
- DNS change alerts
- Regular DNS configuration reviews
Frontend Security
- Subresource Integrity for all resources
- Content Security Policy implementation
- Regular security scanning
- Immutable deployments
- Frontend-to-contract verification tools
Phishing Protection
- Domain monitoring service
- Typosquatting detection
- Homoglyph attack monitoring
- Takedown service for malicious sites
- User education resources
Access Control
- Role-based access for all systems
- Multi-signature requirements
- Regular credential rotation
- Access monitoring and alerting
- Privileged access management
Implementation Priority
For projects with limited resources, implement these security measures in the following order:
- Registry locks and hardware MFA for domain registrar
- DNSSEC implementation
- Domain monitoring for phishing attempts
- Frontend security controls
- Comprehensive access control system
Conclusion
A truly secure crypto project requires protection at every layer, from smart contracts to the domain infrastructure that connects users to your platform. By implementing this comprehensive security checklist, you can protect against the full spectrum of threats facing modern crypto projects.
Don’t wait until after an incident to address these critical security elements.
